2 Claims. 1 (01. 16-400) My present invention relates to automaticwindow control and more particularly to an automatic control for anautomobile window.

Hitherto much difficulty has been experienced 5 due to the presentconventional arrangement for raising and lowering windows inautomobiles. The mechanism as at present used often becomes stifi and attimes almost impossible to operate especially in the case of the driverwho may have only one hand available for the purpose. At best eitherraising or lowering the window can be done only slowly and requires muchmore attention and force than should be necessary.

With these difficulties in mind I have designed a new window forautomobiles which obviates the above mentioned disadvantages andmoreover has other very attractive features besides.

The principal object of my invention is therefore an improved windowcontrol for automobiles.

Another object is an automatic control which gives much greaterflexibility and speed of operation.

Other objects and novel features comprising the construction andoperation of my invention will appear as the description of the sameprogresses. r

In the drawing illustrating the preferred em bodiment of my inventionFig. 1 is a side elevation of an automobile door having its exteriorsurface removed showing a sliding glass panel'associated with springmemhere.

Fig. 2 is a cross section taken on the line 2-2 of Fig. 1, showing a camcontrol mechanism and Fig. 3 is a cross section taken on the line 3-3 ofFig. 1 showing how the spring extremities are secured.

Referring more in detail to the drawing in- 40 dicates a window glasscontained in a frame member 11 which is slidably disposed within a doorcasing 12. The window and frame 11 are adapted to be lowered or forceddownward by means of the grip 13. Solidly attached to the bottom of theframe 11 are two supporting arm members 14 and 15 having their lowerextremities converging and embedded in a circular block 16 suspendedthereby. The block 16 is provided with a bolt 17 centrally locatedtherethrough and projecting outwards. Rotatably mounted on theprojecting portion of the bolt 17 and adjacent the block 16 are two discmembers 18 and 19 which are lightly held together by means of the nut20. Located through the peripheries of the disc members 18 and 19 aregrooves 21 and 22.

Vertically'dis'posedadjacent-either inner side of the door casing 12 aretwo spring members 23 and 24 having central coil portions 25 and 26 andopposed end portions 27 and 28 diagonally extending upwards and passingthrough the grooves 22 and 21 respectively. Located adjacent the coilportion 25 and 26 is a second set of coiled springs 29 and 30whichencircle the upwardly extending portions 27 and 28 and are seatedagainst washer members 31 and 32. The washer members 31 and 32 areadapted to bear against the discs: 18 and 19 and to be compressedbackward against the springs 29 and 30.

Internally mounted adjacent the right edge of the door casing 12 is ashaft 33 extending inwardly towards the window 10. Solidly mounted onthe inner extremity of the shaft 33 is an offset cam. 34. Somewhatcentrally located on the shaft 33 is a lever member 35 solidly attachedthereto and extending upward. Horizontally attached to the extremity ofthe lever 35 is a cross arm 36 having its end portion terminating in abutton 3'7. Recessed against the lever 35 and encircling the shaft 33 isa coiled spring 38 adapted to be compressed inward when the lever 35 ispressed forward at right angles to it. The face of the cam 34 is soconstructed that both release and brake control are possible bydifferent adjustment of pressure on the button 37 which actuates the cam34 from the shaft 33. The normal position of the button-35 is'maintainedoutwardly by the coiled spring 38. When slight pressure is exerted uponthe button 37, the normal braking action of the cam face against thewindow frame 11 is proportionately relieved, further pressure on thebutton results in an unimpeded sliding of the window as actuated by thespring and a final strong pressure on the button will cause the cam 34to act as a positive brake again.

In operation assuming that the window is in a closed position to startwith, it may be pulled downwards by the hand of the operator inserted inthe grip 13. The cam is so designed that downward travel of the frame 11will not be affected by it yet an upward return is positively preventedfor any point to which it may be desired to lower the window to. As theframe slides down, the spring portions 27 and 28 advance through thegrooves 22 and 21 respectively with the disc 19 adjusting itself incounter-clockwise rotation and the disc 18 in clockwise rotation. Whenit is desired to return the window to a closed position, it is onlynecessary to remove the braking action of the cam 34 and allow thecoiled springs 25 and 26 to elevate the window as controlled by thebutton 37.

While I have shown a particular form of spring motivation in connectionwith the double acting cam, it is to be understood that variousmodifications may be resorted to in this connection while stillcontinuing to adhere to the spirit of my invention.

Having thus described my invention what I claim is:

1. In a door having a window frame slidably disposed therein andprovided with a cam control mechanism engaging with the side of saidwindow through said door, a closing mechanism comprising a bracketmember centrally fixed to the lower edge of said window frame, a shaftmember horizontally located through said bracket and provided with discmembers rotatably mounted thereon and lever springs internally locatedagainst the sides of said door with the lower extremities anchored tosaid door and further having each of the upper ends slidably securedthrough one of the said disc members respectively. 2. In an automobiledoor having a window frame constructed therein and a window slidably'disposed in said frame and further provided with a friction controlmechanism engaging with said window through said frame, a liftingmechanism for said window comprising a bracket centrally fixed to thelower edge of said window having a block member suspended therefrom, ashaft member horizontally located through said block and having circularplates rotatably mounted thereon adjacent said block, said plate membersprovided with elongated slots through their peripheries, and leversprings having lower extremities anchored in said door and the upperextremities respectively engaging in a slidable manner through a saidelongated slot of a circular plate.
